Pressure reflief valve replacement concave LF bursting disc / rupture disk for safety

Pressure reflief valve replacement concave LF bursting disc / rupture disk for safety​ 

The bursting disc safety device is a pressure relief device which is controlled by the pressure difference and has an effect on the pressure relief and pressure relief device with no more closed.Its role is to prevent the pressure equipment in the operation process of the sudden change in pressure, to reach the pressure equipment can not bear, the bursting of the safety device, with the release of pressure, pressure equipment within the pressure to reduce, safe access to security.

The basic structure types of bursting disc safety device produced by our company are: flat bursting disc, conventional domed disc, reverse domed bursting disc and so on.

· Features

composite bursting disc, composed of a strength film, a sealing film and other components. For the situations where the back pressure needs to be withstood, a support shall be added. Holes and slots (radial or circumferential) are made in the strength film and back support film to weaken the material strength. The tensile failure occurs in the cross-section with minimum pitch when over pressure.

· Broad range of application, and can choose the corresponding assembly according to different burst pressure and vent area.

· Manufacturing ranges depend much on material strength.

· Designed for gas, liquid service

· Suitable for high temperature and pressure conditions.

· Maximum operating pressure equal to or less than 70% of the minimum burst pressure, and not suitable for pressure pulsating conditions.

· Fragments on burst.

· Short service life and easily cause creep deformation and fatigue damage

· Obvious temperature effect may cause burst pressure fluctuation. The temperature goes up while burst pressure declines.
